Abstract
Background: Prospective studies that investigated the influence of glycemic control in the progression of periodontitisand tooth loss (TL) during periodontal maintenance therapy (PMT) programs have not been previously reported. The aim of the present study was to evaluate associations between glycemic control status and the progression ofperiodontitis and tooth loss among cohort PMT individuals. Methods: A total of 92 individuals, all recruited from a prospective cohort with 238 participants under PMT, participated in this study. Diabetes control was assessed by percentage of glycated hemoglobin (HbA1c). Individuals were matched for gender and smoking and were divided into three groups: 23 diabetic individuals with poor glycemic control (PMC), 23 diabetic individuals with good glycemic control (GMC), and 46 non-diabetic controls (NDC). Full-mouth periodontal examination including bleeding on probing (BOP), probing depth (PD), and clinical attachment level were determined at all PMT visits during a 5-year interval. Results: Progression of periodontitis and TL were significantly higher among PMC when compared to GMC and NDC. The final logistic model in final examination included: (1) for the progression of periodontitis - HbA1c ??6.5% (Odds ratio [OR]=2.9), smoking (OR=3.7), and BOP in more than 30% of the sites (OR=4.1); (2) for tooth loss - HbA1c ??6.5% (OR=3.1), smoking (OR=4.1), and PD 4-6mm up to 10% of the sites (OR=3.3). Conclusion: PMC individuals presented higher progression of periodontitis and tooth loss when compared to NDC and GMC individuals, especially among smokers. This result highlights the influence of the glycemic control in maintaining a good periodontal status.
